Problem with GUI slider

Hi all

I have problem with GUI slider. I ned
min= 1
slider step = 1
max = 20

When change parametars in Property Inspector slider disappears.

How to do this?

Please help me!

Any solution?

Set the min value, then the max, then the step, then the value. If your value is not in between the min and the max, the slider will be invisible.

set(handles.slider1, 'Min', 1);
set(handles.slider1, 'Max', 20);
set(handles.slider1, 'SliderStep', [0.01 0.1]);
set(handles.slider1, 'Value', 10);

If you don't set it that way in your code, then set up the values in GUIDE, but again, value must be between min and max.

thank you!

Or set them all at once in the same SET call; that way you avoid getting
into an invalid state even momentarily, which theoretically could be
user-visible if something were to happen between those SET calls (a timer
callback doing a DRAWNOW, for instance.)

set(handles.slider1, ...
    'Min', 1, ...
    'Max', 20, ...
    'SliderStep', [0.01 0.1], ...
    'Value', 10);
